PURPOSE:To improve the responding performance and operability of an input device to an input by speeding the extraction of an on operation point and improving the extraction precision. CONSTITUTION:An input processor is equipped with a timing generating circuit 30 which utilizes a microcomputer, 8-bit counter 31, 4-bit counter 32, 2-input AND elements 33, 36, and 37, and D type flip-flops 34 and 35. As basic processing, the 8-bit counter 31 extracts the on operation of two make contacts connected to trunk lines X and Z by the 1st decoder circuit 8 and a selector circuit 10. When the on operation is performed at only one position, the Y coordinate of the on position is extracted on the basis of the value of the 4-bit counter 32 and that of the 8-bit counter 31 showing said extracted positions X and Z. |
